V REED roe. LOOMS.

To all cvhom'it may concern: t V p Be it known that I, PAnnjA. WAGNER, residing at Jersey City, in the'co'unty-ot Tludsonand State of New Jersey,'have invented a certain new and useful Improvement in Reeds for Looms, of which the following is a specification.

The object of the invention isto' pro-vide a *1'eed,easi-ly and economically manufactured, in which the dents are "accurately,

' uniformly and closely spaced. Another object is to to Figure 2, showing the ribbon partly folded. i i Figure 4 .is a horizontalsection'of the same. Figure 5 isan edge view of a portion of one convolution or fold, corresponding to Figure 3, and on a greatly exaggerated scale. 7

' 'Siinilar-re'tereime numerals indicate the Y same parts'in allthe figures.

The spacing means for the improved rec d i is a ribbon. of thin metal folded back and 'iiorth upon itself in sharp serpentine "bends or con'volutions, with the dents inserted on Y 1 one face in the spaces between '.*the partiseparated by tions thus formed, and held such partitions. One of suclrribbons receives the upper ends of the dentsrand an ends, within the 1 other receives the lower bands;

' Referring to the drawings, 1 is a narrow ribbon of thin metal having on one face equally spaced wide transverse" scores or grooves '2, and on the "other face narrower grooves 3 midway between; the igro oves 2 The grooves serve as weakened lines {for Each groove is perforatedas at 4 and the ribbon between the grooves is pricked or-punctured as at 5 to produce groups of slight elevations or protuberances on one face of the ribbon. The folding of the ribbon into sharp accordion bends is shown as initiated in Fig-- ures 3 and 4 and completed in Figure 9.

The narrower grooves 3 permit a close fold bywhich the adjacent faces of the ribbon lie in close contact'with each other'toform a series of partitions'fi separated each from the next adjacent by a space produced by I the reverse fold along the wider groove 2. p

Two separated ribbons thus formed re 7 ceive the dents 7 in the spaces between the partitions, with the extreme ends of the dents projectingslightly beyond the rib-' bons, as shown in Figures 7' and 8, and-the sidefacesof thedent-ends are held out of 7 direct. contact with the adjacent inner faces oft the partitionsb by the slight protuberances'fi.

Thus assembled the dents are held in place by lateral pressure on the series with the dents equally spaced, and the spacing may be slightly lessened byapplying suf ficieht pressure to break down or upset the protuberancesb and thus reduce the width f of the spaces in which the dent-ends are received. s

The bands 8 in which the ribbons and dent-ends are mounted each has a channel i 9 receiving the inner projecting folds. of the ribbon at the wider grooves 2', and has .a flange 10 matching the projecting ends of the dents, as in Figures 7 and 8. The

are applied as usual and the iio Whole soldered by dipping or otherwise, the perforations 4t permitting the solder to flow to all the surfaces.

A thin strip 12, preferably of the same width as the band 8, may be applied to cover the outer edges of the dents and the outer ends of the partitions 6 of the ribbons, and soldered in place to afford a finish to this face of the reed. 1

To removea dent, the solder is softened by heat and the strips 12 removed to permit access to the ends of the worn or defective dent which is then removed and a perfect dent substituted. The strips 12 are then replaced and the whole permitted to cool and harden the solder.

The grooves 2 and 3 may be omitted and a plain ribbon employed with or without the perforations 4 and protuberances and other modifications may be made in the forms and proportions of the parts without departing from. the principle of the invention.

1. In a reed, a series of dents separated at their ends by partitions formed by folding a ribbon upon itself.

2. In a reed, a series of dents separated at their ends by partitions formed by folding a ribbon upon itself and compressible means on said partitions between the latter and said dents.

3. In a reed, a series ofdents separated at their ends by a series of partitions formed by folding a ribbon upon itself on predetermined transverse lines. I

4. In a reed, a series of dentsseparatedat their ends by a series of partitions formed by folding a ribbon upon itself in serpentine convolutions, such ribbon having weakened transverse lines determining such folds.

5. In a reed, a series of dents separated at their ends by a series of partitions formed by folding a ribbon upon itself in serpentine convolutions, such ribbon having perforations in the lines of such folds.

6. In a reed, a series of dents separated at their ends by a series of partitions formed by folding a ibbon upon itself in serpentine convolutions, such ribbon having transverse grooves for determining the lines of such folds.

7. In a reed, a series of dents separated at their ends by a series of partitions formed by folding a ribbon upon itself in serpentine convolutions, such ribbon having transverse grooves located alternately on each'face for determining the lines of such folds.

8. In a reed, a series of dents separated at narrow grooves serving to produce said partitions, and said wide grooves serving to produce the spaces between said partitions in which said dents are received. 7

9. In a reed, a series of dents separated attheir ends by a, series of partitions formed by foldlng a ribbon upon itself 1n serpentine convolutions, such ribbon. having equally spaced wide transverse grooves on one face transverse grooves on the other face for e e alternating with equally spaced narrow determining the lines of such folds, said nar- 1 row grooves serving to-produce said partitions, and said wide grooves servingto produce the spaces between said partitions in which said dents are received, and compressible protuberances formed on such ribbon on the faces of said partitions adjacent to said dents. I

10. In a reed, a series of dents separated at their ends by a series of partitions formed by folding a ribbon upon itself in serpentine convolutions, such ribbon having equally spaced wide transverse grooves on one face alternating with equally spaced narrow transverse grooves on the other face for determining the lines of such folds, said narrow grooves serving to produce said "partitions, and said wide grooves serving to produce the spaces between said partitions in which said dents are received, such grooves having perforations therein through said ribbon.

'11. by a series of partitions near their ends, formed by folding agribbon upon itself in serpentine convolutions, and bandseach having a channel receiving the inner folds of its ribbon, and a flange. covering the ends of said dents.

12. In a reed, a series of dents separated by a series of partitions near their ends,

formed by folding a ribbon upon itself in serpentine convolutions, bands each having a channel receiving the inner folds of its ribbon, a flange on said band covering the In a reed, a series of dents separated extending ends of said dents, and a strip on each of said bands ribbon.

In testimony that I claim the invention above set forth I afiix my signature.
